Our present invention relates to machines Afor makingbelts and strapsirornV a stripof ii'exible material.

It isan object of 'our present invention to 'pro-4 vide a machine with which 'itis possible to automatically out belts and straps from strip material..

It `is also an object of our present invention'to" provide an automaticmachineofthe above type which makesit possible'to automatically cutnot only `the belts and strapsto 'their proper length,

but also to Vcut intothe `same thenecessary holes for the buckle It is finally, also an object of our present inventionto equip an automatic beltor strapmakingA4 machine with .means for adjusting the length ofA the belts and straps produced by this machine.

With the above objects in vievv, our. present in;

vention mainlyV relates to 'a machineior making 'A belts of a strip of iiexible material and' consists in combination of a series of cooperating elements,

namely: rotatable cutting means adapted' to outa strip of fiexiblematerial into belts, rotatable i transporting means adapted to transportthisstrip of flexible material to the above m'entionedrotatA able cutting means, continuously rotating Vdriving connecting means adapted to connect periodically the above mentioned continuously rotating driving means Withtherotatable transporting means so as to cause alternative periods of transportation and periods `o ^standstill ofv these transporting` means.' and second connecting means adapted to* connect periodically the above!" mentioned continuously rotating driving means Witlrthe rotatable outtingmeans so as` tocauselalternative periods of cutting and periods ofstand-still `of these rotatable cutting means.

In accordance with a preferred embodiment vof our present invention; the rotatable transporting Similarly, thesecond connecting means men A tioned above consist of second connecting gear 25 means for drivingthe above rotatable cutting i means and rotatable transporting means, iirst means driven by the continuously rotating, driving means" and adapted to drive the rotatable cuttingrollers andot second .operating means adaptedfto connectperiodically these second connecting ,gearA means with the rotatable cutting rollers so as tocause, alternative 'periods ci .cutting andlperiods oi "standstillof these cutting rollers.

We have found it advisable to use `as rst co`n.

UnectingA gear means aiirst gear train and as flstfoperating means a clutch mechanism adapted `-to4 operate as set forth above.

VWeA have also found it advisable' to use assecond connecting gear means a second 'gear i'.r a`in`.andf Aas second ,operatingmeans a Geneva. `Crosstypetf mechanism adapted torotate the cutting rollers..

as setorth above. n

Inv order .totenable adjustment oi the length of the belts producedbyour new machine, we `pro-- vide manually .adjustableregulating means com-l bined with the iirstfoperating .means deiined above,. e. g., combined with the clutch mechanism and construct these regulating means so that they are adaptd .to .vary the length .of the periodical connections between .the first Vgear train and the. 'rotatable transporting rollers, thereby causing.

variationof the lengthA of-the consecutive transportation periodsofthese rollers and causing alsoA variationof` the length of the flexible stripmaterial transported during each `of-.these consecutive transportation periods.

It should be stressed that it isof-great impor-A tance `.that the second operating` means-dened above, e. g.,vthe Geneva Cross type mechanism is5 adaptedto connect the rotatable .cutting -rollers With the driving Vgear train onceduringseach ,of the transportation periods .of .the rotatable transporting rollerssoasto `cause one period of cutting l of tlierotatable cuttingrollersduring each of the transportation periods of the rotatable transportling rollers.

In order. to prevent unintentional turning of the transporting rollers during their periods or. standestilLtve found it advisable to combine with" l lthese transporting'rollers brake means so 4as-to 45prevent. unintentional. turningof the same during their'. `periods of stand-still.

Similarly, we provide stop. means combined.` with a Geneva Cross type mechanism .so as .to

prevent unintentional turning of the rotatable 'cuttingfrollers during their periods of stand-still" Our new "machine mightbe used for producing j belts and straps of various types. We foundthat* it is particularly adapted for production or belts* of "conventional type-,-i. e.; of belts having `near one .end otV the -samepne longitudinal holeU through which the buckle pin is passing when it is secured to the belt, and a series of ho-les near its other end for closing the belt in usual manner.

In order to produce these holes simultaneously with cutting the belts to their proper length, we found it advisable to provide rotatable cutting rollers having cooperating peripheral faces, at least one of which is provided with various cutting members, e. g., cutting projections so as to obtain the desired results. These cutting projections provided by us on the cutting rollers are two differently shaped longitudinal cutting projections arranged transversely to the direction of rotation of the cutting rollers and adapted to cut the flexible strip material passing through these cutting rollers into a series of belts having differently shaped ends, a plurality of small hole cutting projections arranged on one side of these differently shaped longitudinal cutting pro-jections in direction of rotation of the cutting rollers so as to be adapted to out the necessary belt holes into each of the belts cut by the above mentioned differently shaped longitudinal cutting rollers, and one longitudinal cutting projection arranged on the other side of the differently shaped longitudinal cutting projections and extending in direction of rotation of the rotatable cutting rollers so as to be adapted to cut into each of the belts produced by the cutting rollers the longitudinal hole necessary for securing the buckle to the belt.

The novel features which we consider as characteristic for our invention are set forth in particular in the appended claims. The invention itselfhowever, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of speoic embodiments when read in connection with the accompanying drawings, in which:

Fig. 5 is a .partial front view of the machine shown in Figs. 1 to 4 similar to the front view shown in Fig. 1, with the transporting rollers disconnected from the driving means;

Fig. 6 is a rearview of the machine shown in Figs. 1 to 5, seen in direction of arrow 6 of Fig. 2;

Fig. '7 is a cross section through a .part of the regulating means shown in Fig. 1, along line 'I-1 of Fig. 1;

Fig. 8 is a sectional view along line 8-8 of Fig. 3; and

' Fig. 9 is a top view of belts produced with a machine of the type shown in Figs. 1 to '7.

As shown in the drawings, our new machine comprises as main elements the two transporting rollers I0 and Il which cooperate with the transporting table I2 provided with a feeding channel not .slrown in the drawings, and the cutting .rollers I3 and I4 to which the strip material I5 guided by the roller It is fed by the transporting Irollers I0 and II.

In order to drive these transporting and cutting rollers, we provide an electric motor I'I connected by shaft I 8 with the continuously rotating driving gears I9 and 29.

Gear I9 is permanently in mesh with gear 2| turnably carried by the pin 22,1irmly secured to the arm 23. This arm 23 is turnable to and fro in direction of arrow 24 about the ,axis of shaft I3 so that the gears i9 and ZI are permanently in mesh despite turning of the latter gear during movement of the arm 23 supporting it.

The gear 2I is in mesh with the gear 25 rotatably carried by shaft 2t, when gear 2| is in its operative position shown in Fig. 1. When gear 2| is turned together with arm 23 into its in operative position shown in Fig. 5, the gears 2| and 25 are out of mesh.

The gear 25'is permanently in mesh with the gear 2'I secured to the shaft 28 carrying the transporting roller IU. Thus, when gear ZI is in its position shown in Fig. 1, and motor l'i operates,

Y the transporting rollers IEI and 5I are turned by means of shaft I8 and the gear train consisting of the gears I9, 2l, 25 and 2l.

In order to obtain alternating periods of turning and stand-still of the transporting rollers, we provide operating lmeans to turn periodically the gear 2I from its operative position shown in Fig. 1 into its inoperative position shown in Fig. 5 and back, whenever required.

These operating means include the gear 12d which is in mesh withand driven by the gear 223 mentioned above. These operating means include also the ,pin 3B mounted on gear 29 so as to be adapted to engage the projecting member 3| mounted on arm 23.

Furthermore, we provide on gear 29 a disc shaped member 32 arranged coaxially with gear 29 turnably relative to the latter. This disc 32 carries a projecting pin 33 provided with a slanting face 34 as clearly shown in Fig. '7.

The projecting pin 33 is arranged so as to be adapted to engage with its slanting face 363 the lever member 35 pivoted to the supporting frame 3b of the machine by means of pivot 3i as clearly shown in Figs. 1 and 2. The spring 33, clearly shown in Fig. 2, is provided at its Yone end 39 to the supporting frame 36 and at its other end 4) to the lever member 35 tending to turn the same in direction of arrow 4I.

The lever member 35 is provided With a cutout i2 adapted to engagethe projection 43 provided on arm 23 when the same is in theV position shown in Fig. 5, that is, when the gear ZI and the arm 23 are in inoperative disengaged position.

The disc 32 together with the projecting pin 33 might Abe adjusted relative lto gear 2i! yby turning them about the shaft le carrying both the disc 32 and the gear 29. Y

In order to secure the disc 32 in diierent positions to the gear 29, we provide on gear .2@ an adjusting screw t5 and cutan arcuate groove 45 into disc 32 cooperating with screw d5 as shown in Fig. 1.

The above described operating means operate as follows:

In the position shown in Fig. 1, the spring pressed plunger l will press the arm 23 upward in direction of arrow il and thus force gear 2i into mesh with gear 25. Thus, in this position the gears It, 2l, 25 and El will be in'mesh and the transporting rollers i@ and l i will rotate when motor I'I rotates gear 2t.

During such operation of the machine, the gear 2S rotating in direction of arrow 49 will turn the assenso by `pin 3u Jinsclo'ckwiserzdirectioni:intoltlre position; shownin` Figf.;r:- In-.this:position1'theifprojectiorr 4e proridedionr armiwilk engagezthe `:cut-out 142" onflever'51andvthisfleverzwillathus'hold theearnr 23;.itogether3with .the 4'gea-rr :2 I'f sin" the finoperative|` position shown in Fignlf'sf This-will: resultiin. stopping ioitheY :transporting rollersl'and I I-.ze At the sametiinethe gear-.29. will continue .to-rotate in .directionofv 'arrow'-49 untilithef slanting :aoertilf of.` the `projecting pin 331 engages: the: top rend' 55 totrthe lever 3 5r and pushesf thexsarne outward'in thewdirectionzof:arrowilli;` Suchzrmovement :or .the .lever 135 :fwillifresult in; slidingsout of` the projection 43 zfrom thefcut-out" 4'2 andtpermitspringnwtonrove thearina23 to-` gether. witlifgear .=2 I1' infdire'ctionLof.` arrow a4 8 1vhack into the. operative positioncshovminrlig; ,1.:..

The ftran'sporting: rollers-1.` will i start -tofrotate again as soon as the projecting pin 30 contacts again the lever 35 as explained above.

4 Thus, one complete cycle `of operation of the machine consists of the following phases:

First phase:'The transporting rollers will rotate alone and the cutting rollers will be in standstill. During this phase. of operation the strip material will be fed by the transporting rollers between the cutting rollers which are provided with a receding peripheral portion so as not to engage the strip material during this phase of the operation.

Second phase: The cutting rollers will start to rotate and the transporting rollers will continue to rotate. During this phase of operation the strip material is fed by the transporting-rollers between the cutting rollers and cut by the same. Third phase: The cutting rollers stop to turn and the transporting rollers continue to rotate. During this phase of operation the necessary adjusted length of strip material is fed by the transporting rollers through the cutting rollers without being cut by the same.

Fourth phase: The transporting rollers stop to rotate and the cutting rollers remain ein standstill. During this phase of operation the continuously rotating parts of the machine continue to operate so as to enable adjustment of the length of the single strip portions transported during each cycle of operation as set forth above.

After the fourth phase of operation the transporting rollers will start to operate again and a next cycle of operation will start. l

With a machine of the type described above it is possible to produce automatically belts of the type shown in Fig. 9. For this purpose one of the cutting rollers, for instance, cutting roller I4 is provided with two cutting projections 63 and 54 which cut the ends 65 and 66 of the belts shown in Fig. 9. Furthermore, roller ld is provided with a plurality of cutting/projections 61 by which the belt holes 68 are punched. Finally, the roller I4 is also provided with a longitudinal cutting projection 69 by which'hole 10 for the pin of the belt buckle is punched intov the Vstrip material used for the belts.

It will be understood that each of the elements described above, or two or more together, may also nd a useful application in other types ofv machines for manufacturing belts and straps differing from the types described above.

While I have illustrated and described the invention asV embodied in automatic belt manufacturing machines, I do not intend to be limited to the details shown, since various modifications and structural changes maybe made without departing in any way 'from the spirit oi my invention.

Without further analysis, the foregoing will so fully reveal the gist of my invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the stand-point of prior art, fairly constitute essential characteristics of the generic or specic aspects of this inventionV and therefore, such adaptation should and are intended to be co-mprehended Within the meaning and range of equivalence i the following claims.
